The mass transfer rate of hydrogen in tetralin and hydrogenated SRC II liquid was studied in a stirred vessel at 606-684 K and 7.0-I 3.5 MPa. Experiments were carried out using a newly developed in-situ hydrogen probe made of semi-permeable nickel membrane. The effects of stirrer speed, liquid heigh

✦ Synopsis
Interfacial tension is unique in the sense that it relates to the interface between two immiscible fluid phases. Hence, interfacial tension between the fluid phases can be used to infer a great deal of information about phase equilibria such as solubility, miscibility and mass transfer interactions between the two bulk fluid phases in contact. In this paper, we examine the utility of interfacial tension to characterize miscibility and mass transfer mechanisms in complex hydrocarbon fluids at elevated pressures and temperatures. This study also provides a new method to estimate the dynamic interfacial tension and miscibility by incorporating counter-directional diffusivities into the traditional Parachor model.
La tension interfaciale est unique dans le sens qu'elle est reliée à l'interface entre deux phases fluides immiscibles. Ainsi, la tension interfaciale entre les phases fluides peut être utilisée pour déduire beaucoup d'information sur les équilibres de phases, tels que les interactions de solubilité, miscibilité et transfert de matière entre les deux phases liquides brutes en contact. Dans cet article, on examine l'utilité de la tension interfaciale pour caractériser les mécanismes de miscibilité et de transfert de matière dans les fluides d'hydrocarbures complexes à des pressions et des températures élevées. Cette étude fournit également une nouvelle méthode pour estimer la tension interfaciale et la miscibilité dynamiques en introduisant des diffusivités contre-directionnelles dans le modèle de Parachor traditionnel.
